April from Phoenix, Arizona writes

Is Permethrin SFR 36.8% safe to use in succulent pots?

I have a fungus gnat infestation. Thank you.

Answer:

Permethrin SFR 36.8% is not labeled for use on container plants so we cannot recommend it.  We would recommend something like Bifen IT instead which is known for being super gentle on plants and can be used as a soil drench.  The best option with fungus gnats though is to allow the soil to dry out completely as this will kill any larvae in it.
